- 短信的发送需要GSM模块和处理器协作完成,GSM模块与ARM处理器通过串口连接,处理器向串口发送接收AT命令与GSM模块形成通信回路。中文短信的发送采用PDU模式,根据PDU模式标准形成PDU发送包,实现短信发送。本文根据无线电话项目的短信发送模块的实现开发流程编写-Send text messages need to GSM module and processor collaboration, GSM module and the ARM processor through the seri
RS232
- RS-232、RS-422与RS-485都是串行数据接口标准,最初都是由电子工业协会(EIA)制 订并发布的,RS-232在1962年发布,命名为EIA-232-E,作为工业标准,以保证不同厂家产品 之间的兼容。RS-422由RS-232发展而来,它是为弥补RS-232之不足而提出的。为改进RS-232 通信距离短、速率低的缺点,RS-422定义了一种平衡通信接口,将传输速率提高到10Mb/s, 传输距离延长到4000英尺(速率低于100kb/s时),并允许在一条平衡总线上连接最
